JP6763714B2 - Structure with induction sign with phosphorescent or fluorescent material - Google Patents

Description

The present invention relates to a structure comprising an induction sign with a phosphorescent material or a fluorescent material.

In case of a disaster at night or in the dark such as no lighting, guide signs equipped with light emitters such as phosphorescent materials are installed on the floors and roads of structures such as buildings and roads, thereby being guided. It has been conventionally practiced to enable a person (evacuee) to know in which direction to evacuate. For example, Patent Document 1 discloses a building in which a guiding line provided with a phosphorescent body is arranged on a floor surface or a wall surface. In the document, a light emitter is also provided at an evacuation destination such as an emergency exit so that the position can be known even in the dark, and a guidance line is continuously provided up to the evacuation destination. It is possible to know whether to evacuate in the direction of (see Patent Document 1).

On the other hand, in the case of evacuation guidance for the visually impaired, a guidance sign provided with a luminous body is not sufficient. In this regard, Patent Document 2 discloses that a phosphorescent material is provided and a guiding block having a convex portion is arranged on a platform of a subway or the like. According to the document, healthy people can evacuate even in the dark by following the light-emitting guidance block toward an evacuation site such as a subway exit, while visually impaired people can evacuate by using the soles of their feet. Since you can know the existence of the sign by feeling it, it is said that it is possible to head toward the evacuation site by following this. Further, according to the document, the convex portion of the guiding block has a different meaning depending on the shape, such as "stop" for a linear one and "advance" for a dotted one. It is said that by arranging a block having a convex portion indicating "stop" at the edge of the platform, it is possible to prevent a visually impaired person from accidentally falling off the platform (see Patent Document 2).

JP-A-2009-098725 Japanese Unexamined Patent Publication No. 2013-002130

In the event of a fire, especially in the event of a disaster, the floor (road surface, ground) is filled with smoke from a few centimeters to a few tens of centimeters, and the field of view is limited to an extremely narrow area. Is expected. In addition, under these circumstances, the person must crawl on the floor (road surface, ground) to ensure breathing, which further narrows the range of visibility. Is also expected.

In the case of a guidance line as disclosed in Patent Document 1, if the position of an evacuation site such as an emergency exit can be visually recognized, it is known that the guidance line should be followed in that direction, so evacuation should be performed. It is easy to know the direction. However, when the visibility is extremely limited by smoke, the position of the evacuation site such as the emergency exit cannot be visually recognized, and at most a part of the guidance line can be visually recognized. Therefore, which direction should be evacuated? Is difficult to judge. This point is the same for the guidance block disclosed in Patent Document 2, and if the position of the subway exit cannot be visually recognized and only a part of the guidance block can be visually recognized, which direction should be evacuated. It is still difficult to judge whether it is good or not.

Further, in the guiding block disclosed in Patent Document 2, although it is possible to show the meaning without relying on the visual sense due to the difference in the shape of the convex portion, the meaning shown by the block goes further. It is limited to information that there is a risk of falling from the platform, and it is not possible to know the direction to evacuate. Therefore, it can be said that the guiding block disclosed in Patent Document 2 does not fulfill the function of indicating the direction to evacuate to the visually impaired.

The present invention has been made in view of the above problems. That is, the problem to be solved by the present invention is to indicate the direction to evacuate to a person or a visually impaired person who is placed in a situation where the visible range of the light emitting guide sign is extremely limited in the event of a disaster.

<Composition>

(General)

FIG. 1 is a diagram showing an example of the configuration of the structure of this embodiment. The structures in the present invention include buildings such as offices, stores, public facilities (stations, government buildings, etc.), residences, and outdoor structures such as roads, bridges, and parks. This figure shows a part of the appearance of the structure 0100, and the floor surface 0101 of the structure which is a building is provided with a plurality of shapes of guidance signs 0110, 0120, 0130, 0140, 0150. Is shown. As will be described later, each induction sign is provided with a phosphorescent material or a fluorescent material, and is configured to emit light in the dark. In addition, each guide sign has a predetermined meaning according to its shape. In the example of FIG. 1, the substantially circular guide signs 0110, 0120, and 0140 are given the meaning of "keeping the direction in which they came and going straight to the position of the next guide sign", and are substantially isosceles triangles. The shape guidance sign 0130 has the meaning of "advancing in the direction of the apex angle 0131", and the substantially quadrangular guidance sign 0150 has the meaning of "stop once". Therefore, even in a situation where the visibility is limited due to smoke or the like and only one guidance sign can be seen, the guided person can reach the position of the emergency exit 0102, which is the evacuation destination, by moving according to this meaning. be able to. At the time when the guided person starts the evacuation action, it may not be possible to identify which direction corresponds to the "coming direction" by looking at the approximately circular guidance sign, so this situation should be dealt with. In order to make it possible, a guide sign indicating the direction of the emergency exit as conventionally used may be appropriately provided. FIG. 5 shows an example of the configuration of the structure 0500 provided with the guide sign 0560 indicating the direction of such an emergency exit.

In the above example, a predetermined meaning is given only according to the frame shape, but unlike this, in addition to the frame shape, patterns and characters such as guidance marks drawn on the surface of the guidance sign are shown. A predetermined meaning may be given according to the above. Further, the direction to be evacuated may be indicated by a combination of such a pattern or character having a predetermined meaning and a shape having a predetermined meaning.

FIG. 7 is a diagram showing an example of the configuration of the structure of the present embodiment, and shows an example of a structure including a guide sign having a predetermined meaning according to such a pattern or character. In the example of this figure, the guidance with the arrow pattern drawn on the surface together with the guidance signs 0710, 0720, 0740, 0750 which are given a predetermined meaning only according to the frame shape similar to that shown in FIG. The sign 0730 is provided. This guidance sign has a meaning, for example, "after stopping once, proceed in the direction of the arrow".

FIG. 8 is a diagram showing an example of a guide sign having a predetermined meaning according to a pattern or a character. Of these, the one shown in (a) is the same as the induction sign 0730 shown in FIG. 7. In addition, what is shown in (b) is an example of the guidance sign 0810 in which meaning is given using both patterns and letters. For example, "after stopping once, to the position of the emergency exit 10 meters ahead in the direction of the arrow. It has the meaning of "advance". Further, (c) is an example in which such a guide sign and the above-mentioned guide sign having only a frame shape are used as if they were one guide sign, and these signs indicate "in the direction of the apex angle 0821". It has the meaning of "advance 5 meters".

In other words, in the above example, among the guide signs provided in the structure, the guide signs having a substantially quadrangular shape are given meaning not only according to the frame shape but also according to the patterns and characters appearing in the frame. This is an example that is structured so that the rules for understanding are defined. In this example, an example is shown in which meanings are given according to such patterns and characters, but such meanings are not limited to the substantially quadrangular guide signs, but may be given to guide signs of other shapes. It may be made for guidance signs of a plurality of types.

When a pattern or character is represented on the guide sign, it is desirable to provide unevenness or add Braille to the pattern in order to guide the visually impaired.

Returning to FIG. 1, the frame shape of the guide sign shown in this figure is an example and may be another shape, for example, a substantially polygonal shape or a shape in which these are combined. Further, in this figure, an example in which the guide sign is arranged on the floor surface (road surface, ground) is shown, but the place where the guide sign is arranged in the structure in this embodiment is not limited to this, for example, the wall surface of the building. (It may be either an outer wall or an inner wall) or a ceiling surface. However, assuming that the floor surface (road surface, ground) is filled with smoke from several centimeters to several tens of centimeters due to a fire, the location of the guide sign is the floor surface. It is desirable to be at a low position (road surface, ground) or its vicinity.

The structure in the present invention is provided with a plurality of induction labels. This is so that a taxiway for appropriately guiding the guided person to the guiding place can be formed by the combination of meanings of each of the plurality of shapes of the guiding signs. In addition, since it is desirable that at least one guide sign can be visually recognized by the guided person wherever the person is guided in a situation where the field of view is extremely limited due to smoke during a fire, the intervals between installation of the plurality of guide signs Is properly installed from this point of view.

(Induction sign)

FIG. 2 is a diagram showing an example of the configuration of a guide sign provided in the structure of this embodiment. In this figure, (a) is an example of a substantially circular guide sign shown in FIG. 1, (b) is an example of a substantially isosceles triangle-shaped guide sign, and (c) is an example of a substantially square guide sign. The upper row is a plan view, and the lower row is an upper XX line sectional view. The cross-sectional view also shows a part of the floor surface (road surface, ground) of the structure provided with the guide sign.

As shown in FIG. 2A, the induction sign 0210 is configured by providing a phosphorescent material or a fluorescent material 0214 in a recess 0213 surrounded by a frame 0212 of a plate-shaped body 0211 with a frame. The plate-shaped body with a frame means a tray-shaped plate-shaped member having a recess in the center by erecting a frame on the peripheral edge. As the material of the plate-shaped body with a frame, metals such as aluminum and stainless steel, ceramics, resins and the like are used.

The phosphorescent material or the like may be arranged in the dent by, for example, applying a phosphorescent paint or a fluorescent paint, pouring a liquid phosphorescent material or a fluorescent material to solidify it, or attaching a phosphorescent sticker or a fluorescent sticker. .. At that time, a reflective material may be arranged in the recess, and then a phosphorescent material or the like may be arranged in the upper layer thereof. The reflective material is for reflecting the light emitted downward from the phosphorescent material or the like upward to cause the phosphorescent material to emit light with higher brightness, and titanium oxide or the like is used as the reflective material. Further, in order to protect the phosphorescent material or the like from dirt or damage, a transparent protective layer made of transparent glass, transparent resin or the like may be arranged on the upper layer of the phosphorescent material or the like.

For installation of the guide sign in the structure, for example, as shown in the lower part of FIG. 2A, the guide sign is provided with a recess 0201a on the floor surface (road surface, ground) 0201 of the structure, and the guide sign is provided in the recess. Is embedded by bonding with an adhesive or the like so that the surface 0210a of the guide sign forms the same plane as the floor surface (road surface, ground) of the structure. This is intended to prevent aesthetics and the risk of people tripping. The same applies to the guidance sign 0230 shown in (b) and the guidance sign 0250 shown in (c).

On the other hand, in order to guide visually impaired people, it is important to be able to grasp the frame shape of the guidance sign by tracing it with a hand or foot without relying on vision, and thereby to know its meaning. Is. From this point of view, it is desirable that the guide sign is projected from the floor surface (road surface, ground). Details of such a configuration will be described in the next embodiment.

The size of the guide sign needs to be large enough so that the shape can be easily grasped by the naked eye or the touch of the limbs, while the overall shape can be grasped instantly even when the field of view is extremely limited. It is properly designed in the sense that it also needs to stay. Specifically, in the case of a substantially circular guide sign, the diameter of the plate-shaped body with a frame is about 5 to 20 cm, and in the case of a substantially isosceles triangular shape or a substantially quadrangular shape guide sign, the length of one side is about 5 to 20 cm. It is desirable, and more preferably, the above-mentioned dimensions are about 10 cm. Even for guide signs of other shapes, those having substantially the same dimensions are desirable. Further, in that case, the thickness of the plate-shaped body with a frame (height from the bottom surface to the uppermost end of the frame) is, for example, about 2 to 5 mm, and the depth of the recess is considered to be about 1 to 3 mm.

As described above, the guidance sign has a predetermined meaning according to the shape, and this combination can appropriately guide the guided person toward the evacuation site. At that time, in order for the guided person to instantly understand the meaning of the guidance sign and take prompt action, the meaning of the guidance sign is unified nationwide and permeates the people. It is desirable that the sign is as close as possible to the intuitive impression. The example shown in Fig. 1 is considered to match the intuitive impression, and if it permeates the people by being unified nationwide by public standards, etc., the evacuees will be guided. It is expected that it will greatly contribute to the swift evacuation action of. Alternatively, a display unit indicating a predetermined meaning according to the frame shape may be provided so that the guided person understands the meaning of the guide sign, and details of such a configuration will be described later in another embodiment. To do.

(Structure to protect phosphorescent material / fluorescent material)

By the way, in order to make it easier to see the guide sign even when the visibility is poor due to the smoke in the event of a fire, it is desirable that the phosphorescent material or the like is protected from being directly hit by a person or an object and damaged. The transparent protective layer described above is an example of a configuration for that purpose. Further, as a configuration for preventing the phosphorescent material and the like from being damaged, a plurality of shaped protrusions are erected in the recessed portion of the plate-shaped body with a frame, and the phosphorescent material and the like are arranged in the recessed portion other than the protrusions. You may do so.

FIG. 3 is a diagram showing an example of the configuration of the guide sign provided in the structure of the present embodiment, and shows an example of the shape of the structure having such a configuration. As shown in FIG. 3A, a plurality of shapes of protrusions 0315 (only one is coded to avoid complication) stand in the recess surrounded by the frame 0312 of the framed plate-shaped body 031 of the guide sign 0310. The phosphorescent material or the like 0314 is arranged only in the recessed portion other than the protrusion. Further, a transparent protective layer made of transparent glass, transparent resin or the like may be arranged on the upper layer of the phosphorescent material or the like. As a result, for example, even if a person or a vehicle steps on a guide sign installed on the floor surface, the shoes or tires will not come into direct contact with the phosphorescent material or the transparent protective layer due to the protrusions, and the phosphorescent material or the transparent protective layer can be used. Can be protected from damage. The configuration described above is the same for the guide sign 0330 shown in FIG. 3 (b) and the guide sign 0350 shown in FIG. 3 (c).

(Structure for emitting phosphorescent material / fluorescent material with high brightness)

Further, in order to make the guide sign easy to see even when the visibility is poor due to the smoke filling in the event of a fire, it is desirable that the phosphorescent material or the like emits light with high brightness. The above-mentioned reflective layer is an example of the configuration for that purpose. Further, in the present invention, when a method of pouring a liquid phosphorescent material into a recess of a plate-shaped body with a frame to form an induction label is used, the method disclosed in Japanese Patent Application Laid-Open No. 2015-049396 can also be used. Good. In this method, a mixed solution of strontium aluminate-based phosphorescent powder and liquid phenylsilicone is poured and allowed to stand for a predetermined time, and the phosphorescent powder is cured in a precipitated state to form a phosphorescent layer. This makes it possible for the phosphorescent layer to emit light with high brightness.

<Effect>

According to the invention of this embodiment, it is possible to indicate the direction to evacuate to a person or a visually impaired person who is placed in a situation where the visible range of the light emitting guidance sign is extremely limited in the event of a disaster. It is possible to provide a structure with a sign.

<Overview>

In the structure of this embodiment, a plurality of shapes of guide signs are arranged so as to be convex so that a plate-shaped frame can be traced by hand or foot on or near the floor surface (road surface, ground). .. In addition, the installation interval of the multiple-shaped guide signs is 0.5 m to 3 m, which is the interval at which the next guide sign can be visually recognized at the line-of-sight height just near the floor even when the taxiway is filled with smoke. Some are also included in the structures of this embodiment.

<Composition>

(General)

The structure of this embodiment is basically the same as that described in the first embodiment, but in this embodiment, the plurality of shapes of the guide signs included in the structure are placed on the floor or road surface, on the ground or in the vicinity thereof. It is characterized in that the frame of the plate-shaped body is convexly arranged so that it can be traced by hand or foot. The configuration will be described below. Since the remaining configuration is the same as that of the structure of the first embodiment, the description thereof will be omitted.

(Induction sign: convex arrangement)

FIG. 4 is a diagram showing an example of the configuration of the guide sign provided in the structure of the present embodiment, and is shown in the same cross-sectional view as that shown in the lower rows of FIGS. 2 (a) to 2 (c). Is. Of these, in the one shown in FIG. 4A, a part of the guide sign 0410 is embedded in the recess 0401a of the floor surface (road surface, ground) 0401 of the structure by adhering with an adhesive, and the rest of the guide sign is the floor. It is designed to be convex on the surface (road surface, ground). In this case, as shown in this figure, the slope gently descends outward to the guide sign frame 0412 so that a person does not trip over the convex portion or an object may hit the convex portion. Surface 0412a may be formed. Further, in the one shown in FIG. 4B, the guide sign 0420 is adhered on the floor surface (road surface, ground) 0401 with an adhesive so that the entire guide sign is projected. .. In this case as well, an inclined surface 0422a that gently descends outward may be formed on the frame 0422 of the guide sign.

(Induction sign: placement position)

In addition, the placement position of the guide sign in the structure of this embodiment is limited to the floor surface (road surface, ground) or its vicinity. This is a situation in which the present embodiment is filled with smoke from a few centimeters to a few tens of centimeters on the floor surface (road surface, ground), especially due to a fire, and the guidance sign is almost invisible. Furthermore, in order to secure breathing under such a situation, it is assumed that the vehicle must move by crawling on the floor surface (road surface, ground). By arranging the guide sign at such a position, even under such a situation, the guide sign in the immediate vicinity can be visually recognized or traced with the hand or foot, and the next guide can be traced according to the meaning represented by the guide sign. It is possible to move to the position of the sign.

From this point of view, the dimensions of the convex portion are designed so that a person can trace the shape with his / her hand or foot. Specifically, for example, it is desirable that the surface dimension is about the same as that described in the first embodiment and the height of the convex portion is about 1 to 5 mm.

(Induction sign: placement interval)

In addition, it is desirable that the installation intervals of the multiple-shaped guide signs are such that even if the taxiway is filled with smoke, the next guide sign can be visually recognized at the line-of-sight height just before the floor surface (road surface, ground). Specifically, the interval is preferably 0.5 m to 3 m, and more preferably 0.5 m to 1.5 m. "The height of the line of sight just barely on the floor (road surface, ground)" is a few cm to 0.5 m from the floor surface (road surface, ground), which is the usual height of the line of sight when a person is crouching or crawling on the stomach. The height of the degree.

<Effect>

According to the invention of the present embodiment, it is possible to provide a structure provided with a guidance sign capable of indicating the direction to evacuate, even in a situation where smoke is full due to a fire. Become.

<Overview>

In the structure of this embodiment, the emission colors of the phosphorescent material or the fluorescent material are different, and each emission color has a different meaning.

<Composition>

(General)

The structure of this embodiment is basically the same as that described in Example 1 or 2, but in this embodiment, the emission color of the phosphorescent material or the fluorescent material is different, and each emission color has a different meaning. It is characterized by the fact that it is made. The configuration will be described below. Since the remaining configuration is the same as that of the structure of the first or second embodiment, the description thereof will be omitted.

(Induction sign: different emission color)

In recent years, various emission colors such as red, yellow, green, blue-green, and blue are known as emission colors of phosphorescent materials and fluorescent materials. Regarding the phosphorescent material, for example, Japanese Patent Application Laid-Open No. 2011-189558 describes a phosphorescent material in which a small amount of copper is added as an activator to zinc sulfide crystals (the emission color is yellow to red depending on the composition), and a small amount of zinc sulfide. Luminescent material with copper added as an activator (emission color is green), phosphorescent material with aluminate added with europium as an activator or a rare earth element or transition metal as a co-activator (emission color is green or blue) Is disclosed. Further, as a fluorescent material, various emission colors such as red, orange, yellow, green, and blue are known. Therefore, in this embodiment, by utilizing this to make the emission color of the phosphorescent material or the like different and give each emission color a different meaning, the guided person can more easily and surely understand the meaning of the guidance sign. It is something that can be done.

In that case, as in the case of the meaning according to the shape, the meaning according to the emission color is unified nationwide, so that it has permeated the people and matches the intuitive impression as much as possible. Is desirable. For example, when the meaning given to the above-mentioned approximately circular guide sign is "keep the direction of arrival, go straight, and proceed to the position of the next guide sign", among the same shapes, The bluish-green (or blue) luminescent color guide sign simply means "keep the direction you came and go straight to the next guide sign position", and the yellow luminescent color guide sign Can be thought of as "keeping the direction you came from, going straight, and proceeding to the position of the next guidance sign, while paying attention to the surroundings."

Further, the frame shape of the guide sign and the emission color may have a one-to-one correspondence, and the meaning may be given by a combination of these. For example, a substantially circular guide sign may have a blue-green emission color, which may be given the meaning of "keeping the direction in which you came and going straight, and proceeding to the position of the next guide sign." Conceivable. By doing so, it can be expected that the guided person will be able to instantly understand the meaning and evacuate quickly.

Although not included in this embodiment, it is conceivable that the meaning is not given according to different shapes, but is given exclusively according to the emission color. For example, after unifying the frame shape of the guide sign to a substantially circular shape, the guide sign of the blue-green (or blue) emission color says, "Keep the direction you came and go straight, and the position of the next guide sign. The meaning of "Proceed to" is given to the yellow luminescent color guidance sign, "Be careful of the surroundings, keep the direction you came and go straight, and proceed to the position of the next guidance sign." , It is conceivable that the red luminescent color guidance sign has the meaning of "stop once".

<Effect>

According to the invention of the present embodiment, it is possible to provide a structure provided with a guidance sign capable of indicating the direction to be evacuated more reliably to the guided person in the event of a disaster.

<Overview>

The structure of this embodiment is a structure in which a display unit indicating a predetermined meaning according to the frame shape is arranged on the floor surface, the road surface, the ground or its vicinity. Further, a structure in which a display unit indicating such a meaning is arranged on the wall surface is also included in the structure of the present embodiment.

<Composition>

(General)

The structure of this embodiment is basically the same as that described in the first embodiment and the like, but the structure of this embodiment has a floor surface or a road surface having a display portion showing a predetermined meaning according to the frame shape. , Placed on or near the ground. Alternatively, in the structure of this embodiment, a display unit indicating a predetermined meaning according to the frame shape is arranged on the wall surface. The configuration will be described below. Since the remaining configuration is the same as that of the structure of the first embodiment, the description thereof will be omitted.

(Display part)

The "display unit" of this embodiment is for showing a predetermined meaning according to the frame shape, and is arranged on the structure for the purpose of showing the meaning uniquely and objectively. is there. For this purpose, the meaning is typically expressed in letters (language).

FIG. 6 is a diagram showing an example of the configuration of the structure of the present embodiment, and shows the shape of the structure in which the display unit is arranged. Of these, (a) is an example in which the display unit 0660 indicating a predetermined meaning according to the frame shape is arranged on the floor surface in the vicinity of the guidance sign 0610 arranged on the floor surface. The example in this figure is an example in which the display unit indicates a predetermined meaning according to the frame shape in characters, and the wording indicating that the display unit corresponds to a substantially circular guide sign and its wording thereof. The meaning is "Keep the direction you came and go straight ahead to the position of the next guidance sign". It is desirable that this display unit is also provided with a light emitting body such as a phosphorescent material so that the display unit can perform its function even in a situation where smoke is full in the dark. Further, unlike the example in this figure, the display unit may be provided on the corresponding guide sign itself, and in this case, the display portion indicating the correspondence relationship with the guide sign is unnecessary.

Further, FIG. 6B is an example in which the display unit 0660 showing a predetermined meaning according to the frame shape is arranged on the wall surface. The method of arranging the display unit in this case may be basically the same as the case of arranging the display unit on the floor surface, but the display unit on the wall surface can be visually recognized in many cases where the smoke is not filled. Therefore, it is not necessary to be in the vicinity of the guide sign, and it may be arranged on the wall surface as corresponding to the guide sign 0610 arranged on the floor surface as in the example of this figure. In addition, in light of the fact that it is often possible to see guidance signs of multiple shapes at once under such circumstances, it is also effective to be able to list the meanings of all of the multiple frame shapes. Is. FIG. 6C shows an example of the arrangement of the display unit 0660. As a result, the guided person can grasp the meaning according to each frame shape at once, and can take evacuation action more quickly. In addition, such a list display on the wall surface can be expected to have an effect that the unique meaning can be permeated in advance by making it easy for pedestrians to see when passing in normal times.

<Effect>

According to the invention of this embodiment, it is possible to uniquely and objectively show a predetermined meaning according to the frame shape of the guide sign.

<Overview>

The structure of this embodiment is a structure in which a display unit indicating a predetermined meaning according to the emission color of the phosphorescent material or the fluorescent material is arranged on the floor surface or the road surface, the ground or its vicinity. Further, a structure in which a display unit indicating such a meaning is arranged on the wall surface is also included in the structure of the present embodiment.

<Composition>

The structure of this embodiment is basically the same as that described in Example 1 and the like, but the structure of this embodiment is a display showing a predetermined meaning according to the emission color of the phosphorescent material or the fluorescent material. The part is arranged on the floor surface, the road surface, the ground or its vicinity. Alternatively, in the structure of this embodiment, a display unit indicating a predetermined meaning according to the emission color of the phosphorescent material or the fluorescent material is arranged on the wall surface. The configuration will be described below. Since the remaining configuration is the same as that of the structure of the first embodiment, the description thereof will be omitted.

(Display part)

The "display unit" of this embodiment is for showing a predetermined meaning according to the emission color of the phosphorescent material or the like, but the structure is intended to show the meaning uniquely and objectively. The point that it is arranged is the same as the display unit in the previous embodiment. For this purpose, the display unit in this embodiment also typically corresponds to a written meaning (language).

The arrangement of the display unit may be the same as the arrangement described in the previous embodiment regardless of whether the display unit is arranged on the floor surface or the road surface, the ground or its vicinity, or the wall surface. In this embodiment, it is considered effective to unify the emission color of the phosphorescent material of the display unit and the emission color of the corresponding phosphorescent material of the induction sign, which has an intuitive meaning. It can be expected that it will be easier to grasp the attachment.

<Effect>

According to the invention of this embodiment, it is possible to uniquely and objectively show a predetermined meaning according to the emission color of the phosphorescent material of the induction sign.
